Which of these is an equation? A 2y + 7 = 9 B 2x > 3 C 3n + 5 D a2 + 2

nikklg [1K]

Answer:

Option A is correct answer.

Step-by-step explanation:

An equation is having two sides equal. It has an = sign in it.

So, Option A 2y+7 = 9 is an equation as it has = sign in it. So, it is correct option.

All other options do not have = sign in them so, they are not equations.

Solve the following simultaneous equation using either the substitution method or the elimination method, showing all the necess

slavikrds [6]

Answer:

$x=1\frac{83}{91}\\y=-2\frac{73}{91}$

Step-by-step explanation:

#Using the method of substitution and replacement of unknown values.

Given that

$\frac{3}{2}x+\frac{2}{3}y=1...(i)\\and\\\frac{1}{6}x-\frac{3}{5}y=2...(ii)\\$

Express eqtn (ii) in terms of x

$\frac{1}{6}x=2+\frac{3}{5}y\\x=12+\frac{18}{5}y$

Replacing for x in eqtn (i)

$\frac{3}{2}(12+\frac{18}{5}y)+\frac{2}{3}y=1\\18+\frac{27}{5}y+\frac{2}{3}y=1\\18-1=-\frac{91}{15}y\\y=-2\frac{73}{91}$

Substitute y value in eqtn(ii) to obtain x

$Y=-2\frac{73}{91}\\\frac{1}{6}x-\frac{3}{5}y=2\\x=2+\frac{3}{5}(-2\frac{73}{91})\\x=1\frac{83}{91}$

For a particular angle theta, the cosine function f(x) = a cos b(theta) has the following values within one cycle of the functio

Anton [14]

For function $f(x)=a\cos b\theta$ we have that $f(0) =4,\ f( \frac{\pi}{2} )=-4,\ f(\pi)=4$ . This means that period of cosine function is π. Then from the formula for period $T= \frac{2\pi}{b}$ you obtain that $\pi= \frac{2\pi}{b}$ and b=2.

So, the function is $f(x)=a\cos 2\theta$ . If f(0)=4, then $a\cos0=4$ and, respectively, a=4.
Answer: $f(x)=4\cos 2\theta$ .
